Hi all, apologies, I'm a bit of an impostor here, I'm not an MPS owner, but have joined in order to get some advice about another Mazda model. I'm considering getting a petrol CX7 in the next month or two, and I've heard some horror stories about the 2.3 turbo engine which the MPS and the CX7 share; apparently there have been multiple low mileage turbo failures here and in the US, due to carbonised oil blocking the turbo bearing oil feed pipes. Mazda aren't acknowledging it as a design flaw but instead blame it on not following the service schedule to the letter.
So, a quick Google found this forum, and I thought I would ask you good people about your knowledge of this issue - is it something that should put me off buying a petrol CX7, or are there sensible precautions I could take to make sure it won't happen on a car I buy?
Honest John advises replacing the oil feed and return pipes on the turbo; if I bought a low mileage example, did this and a couple of oil flushes with fully synthetic, followed by regular oil changes every 7500 miles; would this give me some confidence that my turbo wouldn't die a premature death?
If so, how big a job is it to replace the oil pipes on the turbo?
And, are there any other issues I should be aware of when inspecting a CX7?
Many thanks in advance
Adam
